Adjust just magenta in flattened file

[docusam]

Hello,
We have a customer sending us a flattened RGB cover. When it converts to CMYK, it comes out more purple than blue. We want to adjust only the magenta to be 85% instead of 100%, so we created an action that utilizes applies a change in the curve. When we run it in acrobat it works as expected, but when put into a switch flow, it washes everything out. Anyone have any ideas as to how we can get this to work in a flow, as it needs to be automated.

Thanks in advance,
Sam

I was actually able to fix this situation by adjusting the color profile to "Generic Enfocus CMYK" and it worked like a charm
